OP imo to sum up missions in this game one could simply say:
"All missions in this game are of fetch or bring nature."
Either you go somewhere to pick something up, even if that is just a kill-token,
or you bring something with you, as seen in powering up the base.
Horrible missions with no evolution, no dynamic aspect. -> Meaningless gameplay -> grind
Then have a look at NPCs, do they evolve? No. Their HP increase and the damage they inflict is upped or their numbers grow.
There are no changing tactics, no communication where they coordinate. They just blindly stumble towards you, with the inability to use their jumpjets. -> unengaging
As a M&K user i am really appaled by the forced aim assist this game has. If you aim near an NPC your crosshair starts to drift towards the hitbox,
use the cutting tool and your crosshair is glued to the rim of the box cover. It is a covered up progress bar that has nothing to do with FPS experience.
Movement is floaty, with no momentum und no acceleration, it just feels wrong. The run animation is the worst, and i played some very old games that even got that right.
Reading that you can't even smartly use the turrets for your legitimate defence is even worse, we already have space NPCs engage based on faction relations...
The only choice so far i have seen this standalone detached mess gives you, is whether you would like to hack a permit locked door, or to overload it via brute force.
OK, you could sneak past enemies too, i guess that qualifies as a choice, if the detection range works like designed...
Again we have a barren, utterly basic foundation that will be left to rot.
So what does Odyssey add? A different flavour of grind, a different point of view, that is it.
